Which demonstrates the application of the Negative Exponent Rule for x^−3 ?

Answer
A
Rewrite x to the negative 3 power as the fraction with numerator 1 and denominator x cubed.
B
Rewrite x to the negative 3 power as negative x cubed.
C
Rewrite x to the negative 3 power as negative the fraction with numerator 1 and denominator x cubed.
D
Rewrite x to the negative 3 power as the fraction with numerator x cubed and denominator 1.

Explanation

The negative exponent rule says that a nonzero base with a negative exponent moves to the denominator and its exponent becomes positive: x⁻³ = 1/x³. So the correct choice is “Rewrite x to the negative 3 power as the fraction with numerator 1 and denominator x cubed.” A negative exponent does not make the value negative.
